Application filed June 19, 1906. Serial. No. 266,077-

To all whom it'may concern:

Be it known that we, WILLARD C. Fosrnn and Lnwrs E. GARRISON, citizensof the United States, and residents of Kalamazoo, in the county ofKalamazoo, State of Michian, have jointly invented a new and usefulashing-Machine, of which the following is a specification.

' a portion in section on dotted line a c Fig.

Flgt.) 2, 4 plan of Fig. 1; Fig. 3, an end view of the ottom of Fig. 6;Fig. 4, interior lan of bottom ofmachine; Fig. 5, Ian of ig. 1 with topand agitator remove Fi 6, side elevation of the agitator with rod brokenaway, and Fi 7' is a plan of Fig. 6.

- he partsof the drawings are pointed out by numerals.

The ordinary metal washtub 8 is provided with a cover 9, which cover hasa door 10, hinged at 11 and 12 and held closed by buttons 13 and 14.Through the door the hot water is put in, and the clothes and theagitator 15 are put in and taken out. A rod 16 of the agitator 15extends up through a bearing-tube 17, attached to the center of thecover 9, and a crank 18 is attached to the upper end of said rod 16 andheld b a nut.

It is our purpose to provide t e machine with the two followingimportant features: first, hot-air and hot-water spaces within the wallof the tub 8 and circling around the tub interior and separated from thesame to re vent the hot water in the machine in w 'ch the clothes arebeing washed from cooling too fast; second, a circular row of flatsurfaces at right angles *teeaoh other in the interior of the machine,where the washin of clothes is being done, in a manner that t e waterwill be splashed squarely against said flat surfaces by the action'ofthe agitator 15, and from which surfaces said water is. reacted backagainst and through the clothes. We accomplish these two purposes orobjects in a cheap and very simple manner by providing the shell'20 andin the manner of its construction. This shell is metal and hoo or drumlike in form and open at top and ottom ends. Its thin wall is bent toform coarse corrugations, which thus appear on both the'outer and innersurface of the Wall, of the shell 20. The size of this corrugated shellis such that it will closely and easily and detachably fit into the tub8, as in Figs. 1 and 5, the apexes of the outer corrugations justtouching the interior of the wall of the tub 8, as in Figs. 1 and 5, andthus establishing a circular row of hot-air and hot-water threecorneredspaces 21 entirely around the tub 8 between its wall and the wall ofsaid corrugated shell 20.

By the touching ofall the outer apexes of the corrugations against theinner wall of the tub more room in a given size construction is had forthe clothes, the shell is held steady in one position, allowing of noside play and crampin and the hot-air and hot-water spaces, t oughseparate from and independent of each other," are located very close toeach other and have more nearly the effect of a sin le s ace around thetub. At the same time y t e same construction the inner flat" surfacesabove described are established, and said surfaces 32, Fig.' 5, do notin any sense serve as rubbing-surfaces for the clothes. The clothes arefreel tossed forth and back in the water in Whic they float by theagitator 15 in a manner to force the water through the clothes, and thusremove the dirt without wear. The raised portion 19 is for attachment ofwrin er. The corrugated shell 20 is provided Wit upper holes 22 andlower holes 23, leading into the spaces 21, through which holes, owingto their small size and fixed location, hot air and steam circulate withmore or less force, acting upon the clothes. The shell 20 is easilydetached for cleaning. The agitator 15 is an important feature, owing toits peculiar construction, by means of which the water is given anupward forward throw, some of it squarely against the inner flat angledsurfaces of the shell 20, from which it reacts forcibly upon theclothes. The body of the agitator is thin and rectangular in form. The uper outer portion of one side at one end, tii e lower outer portion ofthe opposite side at the same end, the upper outer portion of saidopposite side at the other end, and the lower outer portion of thefirst-named side at the latter-named end are all scooped out, as inFigs. 3, 6, and 7. The series of holes 31 through the body of theagitator allow the water to pass through and cause it to operate easler.

To cause the machine to operate easier if overloaded with clothes, weuse a supplemental bottom 27, mounted on a central ivot 24 andball-bearings 25, said pivot 24 oosely fitting a central socket 26 inthe bottom of the tub 8. This bottom has downwardly-extending grooves29, in which are partitions 30, forming pockets 28 for the alls 25. Ifcare is used to not overload the washing-machine, the supplementalbottom can be dispensed with.

In the o eration the supplemental bottom 27 and boi ing hot water areplaced in the tub 8. The cover 9 is placed on, observing to leave thedoor open. As the agitator-rod 16 is loose in its bearing-tube 17, itcan be moved up anddown, so as to handle the door 10 and agitator-without disconnecting them. Now place in a-few clothes and theagitator'15 and close and fasten door 10. Suchsoap may be used as desired. Swingthe crank forth and back about the distance one can reach. for perhas'ten minutes, or it 30 may be entirely revolve now and theninalternation with the short swinging movement. Run the clothes throughthe machine more than once, if desired.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent of the United States of America, 1s

In a washin -m'achine, an outer tub com-, bined with a s ell open attop, and bottom, and made from a continuous metal band corrugated toform the inner and outer flat surfaces described, said shell adapted tofit detachably into the tub, the outer apexes of-itscorrugations touchinthe inner surface ofthe tub-wall making 1; e three-cornered, separated,inde endent, hot-air and hot-Water spaces close y located end toend toeach other around the tub interior, and the small holes near the top andbottom of the shell leading through the same, substantially as setforth.
